TECH FEATURE Ballast water management systems footprint (and it comes in smaller mod- els), so normally it’s easy for the shipyard to bring the equipment into the pump room or the engine room; they don’t have to cut holes in the deck or inside the ship.

During our integration engineering we can provide isometrics for all the piping, so the shipyard can prefabricate the spools so that when the vessel comes in the yard it’s a relatively easy effort to install all that piping. If the vessel owner wants to keep the time they spent at the ship yard as short as possible, a large part of the instal- lation can be done during voyage.

What about compliance?

Giles Candy Compliance is not talked about all that much The next step is biological compliance and SGS recently is- at the moment. From the IMO’s point of view, we’re in the sued a study completed with the Australian authorities show- experience building phase. So it’s no harm, no foul really at ing more than 30% of discharges were non-compliant, non- the moment. In the U.S. it is much more a paperwork exercise. compliance by over an order of magnitude for zooplankton.

There is very little biological analysis being completed. And There is an army of compliance monitoring device companies in times of COVID, I think as long as there’s not gross non- proffering all sorts of solutions for quick analysis of biologi- compliance, things are relatively relaxed. This is odd for a cal load on the discharge and the standards are very high. This convention that was fnal in 2004, as here we are in 2021, and is something that’s underestimated and you can be starting we still don’t actually know how compliance is going to be with a million zooplankton per cubic meter, quite regularly, a assessed. It is on the agenda for MEPC. hundred thousand zooplankton per cubic meter. And you have

And I would think by ‘24, maybe ‘25, there will be some to get down to less than 10. So this is a very high-performance hard guidelines for assessing compliance, but there are really treatment in order to succeed. And if you’re just relying on two forms of compliance. One is technical and the second is flters for that, those flters have to perform really well all the biological. We don’t have any real biological metrics or en- time. InTank is designed to be robust enough to work without forcement at the moment. a flter. Whatever the water quality, the operator has complete

There is some technical enforcement. You’ve got to have a control over compliance, both technical (TRO discharge) and type-approved system on board and it should be working and biological (D2 performance standard)
